It must be considered, in the plastic deformation pressure of practical heading process except frictional force which was analysed by many investigators, that it is influenced by solid restriction, flowing restriction, solid restriction due to flowing and unequal deformation. In the first place the strain hardening curve is presented, which is derived from the tensile test and the designed degree of working, and which makes it possible to guess nearly the allowable range of deformation in the heading process and also the heading pressure. In order to obtain more exact pressure, a theoretical formula is derived, considering the above-described various conditions of practical deformation. It is concluded in this report that the experimental data of working pressure coinside approximately with the data based upon theoretical calculation.
